The red bird is a RIRx probably and is between 12-15 weeks old. The lady I got it from had 2 hatches 3 weeks apart and I don't know which one this came from. It is a bit smaller than the other 4 chickens I got at the same time but RIR are smaller, right? The comb is not much bigger than the light colored one but the wattles are larger. I already have 1 roo I have to rehome out of this bunch. I hope I don't have another.
